For some reason, the downloadable version didn't work as-is for me. I had to replace the shaders with the ones from Bee Magic or else it wouldn't render.
That is odd. I just checked, and the Sea Magic shaders are almost identical to the Bee Magic shaders (minus a newline here and there and some different constants.) I have a few guesses as to what might be causing this, but none of them seem likely to me.
